The six agile, crab-like legs allow the robot to adapt to the changing seabed soil, bounce on the ground without causing damage, and circumvent obstacles.“This bio-inspired robot can hop and jump in broader areas through a spring-loaded mechanism,” project scientific coordinator Marcello Calisti told Sant’Anna di Pisa magazine.“The spring has a simple structure, energy storage and release, and simple control so the robot can jump through an instantaneous contraction of the spring. The crab-like legs include ankle joints which have good jump performance. Our experiments show that the robot can achieve a smooth jump. Long-exposure images without background blurring demonstrate stability.”The robot is capable of adapting to the changing seabed soil.

By clogging sewers and providing breeding grounds for mosquitoes and pests, plastic waste — especially plastic bags — can increase the transmission of vector-borne diseases like malaria.While the issue has received increased attention in recent years, there is still no global agreement to tackle marine litter.Watch: Your Biodegradable Bag Might Not Degrade as Fast as You’d ThinkMore on Consume More Than 70,000 Plastic Particles a YearDead Whale Found With More Than 80 Pounds of Plastic Bags in Its StomachTexas Coast Has More Ocean Trash Than Any Other Gulf State, Study Sayslast_img
